A Sonicwall, SIP and an Altigen Server

Posted on 2010-01-08
Last Modified: 2013-11-16
We have just purchased a sonicwall and got it all setup identical (as far as we can tell) from our old Astaro firewall. We got everything working properly save for one factor.

Our phones will not work externally. People can't call in and we can't call out. I've been woking on this for the past 6 hours and unfortunately, sonicwall won't help us due to contract issues. I'm told it's an issue with the SIP timings, but I can't seem to get it to work properly. Help!

    Have you opened up SIP pots on your firewall?

    Also, I would prioritize your SIP traffic in your firewall rules.

    Accepted Solution

    We figured out the issue. It was due to the Altigen server having issues. We have contacted Altigen and will get this fixed. Turns out I had everything set up properly aready in the Sonicwall.
